content discovery is one of the fundamental issues that determines the architecture and performance of content distribution networks based on peer-to-peer (p2p) networks. to administrate the costs and discoveries, peers of a p2p network communicate with each other by one or more overlay layers. the condition of node’s relations in overlay networks, have a great impact in efficiency of networks....

A common feature of content discovery applications is the ability of users to save and organize digital items into collections, e.g., images into photo albums or songs into playlists. Understanding how these collections grow over time is important for user retention and collection as well as item recommendation. Here we study factors that affect collection growth over a long period of time. We ...

While prior work on context-based music recommendation focused on fixed set of contexts (e.g. walking, driving, jogging), we propose to use multiple sensors and external data sources to describe momentary (ephemeral) context in a rich way with a very large number of possible states (e.g. jogging fast along in downtown of Sydney under a heavy rain at night being tired and angry). With our approa...

The mobile Internet is a massive opportunity for mobile operators and content providers, but despite significant improvements in handsets, infrastructure, content, and charging models, mobile users are still struggling to access and locate relevant content and services. The core of this so-called content discovery problem is the navigation effort that users must invest in browsing and searching...

The recent advent of broadband Internet has led to a convergence of the Web, multimedia, and social media technologies, and revolutionized the TV content consumption. It facilitates users not only watching the TV content, but also accessing personalised information, generating new content, socialising with others, and expressing their emotions. This demonstration showcases the research prototyp...

As part of a Distributed Information Retrieval system a description of each remote information resource, archive or repository is usually stored centrally in order to facilitate resource selection. The acquisition of precise resource descriptions is therefore an important phase in Distributed Information Retrieval, as the quality of such representations will impact on selection accuracy, and ul...

The huge and exponentially growing diversity of digital material confuses the users who are confronted to the difficulty of choosing the right and appropriate document or information. On the same way the federation of Learning Object Repositories could conduct to the same difficulty while wanting to obtain a critical mass of learning object in order to facilitate their reusability. In this pape...

This paper presents small world architecture for P2P networks (SWAN) for content discovery in multi-group P2P systems. A semi-structured P2P algorithm of SWAN is utilized to create and find long-range shortcuts toward remote peer groups. In SWAN, not every peer node needs to be connected to remote groups, but every peer node can easily find which peer nodes have external connections to a specif...
